Stacked layers of oxidized graphene could be used to store hydrogen fuel for cars and other applications. So say researchers in the US who have made graphene-oxide frameworks (GOFs) that can hold roughly 1% of their weight in hydrogen. This value is 100 times better than graphene oxide itself and compares well with MOF-5 (the most studied metal-organic framework to date for hydrogen storage), which absorbs about 1.3 wt%.
